The United Nations Handbook is the only comprehensive printed guide to the United Nations system and how it works. The handbook summarises all United Nations organisations and provides essential information about their aims, structures, and membership. It is a useful reference tool for delegates, diplomats, foreign ministry officials, academics, media, and members of the public. The handbook has been published annually since 1961 by the New Zealand Ministry of Foreign Affairs and Trade. It symbolises New Zealand’s longstanding and practical commitment to the United Nations.

The United Nations Photo Library holds a collection of approximately 800,000 photographs dating back to the mid-1940s chronicling the history of the Organization and its work. The collection includes coverage of historic UN meetings and events, as well as a wide array of field coverage from its earliest days. The Photo Library's mission is to make its collection available to media organizations, governments and non-governmental organizations, researchers and civil society at large, in order to foster public understanding of the work of the United Nations and its goals.
